Hi,
I'm on an Asrock Fatal1ty Gaming K6 Z370 with the latest BIOS with an i7 8700K with the Intel UHD 630. I'm trying to increase the video memory allocated to my IGPU. I'm doing exactly what is being done in this video here how get more dedicated video memory on PC - ASrock - YouTube, changing the "Share Memory" setting under Chipset Configuration. However, windows reports 128M as the video memory no matter what option I choose in the bios.

Can you please help me, is there some detail I'm missing? Thanks :)
